On one hand, it's possible that keeping Yunzi with us will give us time to talk about her cult's problems. Thing is, the last time we made choices with the intention of learning more about the Fire Cult, Jing didn't go into the issue at all, out of respect for Yunzi. Yunzi and the Fire Cult are also most likely to going hate us for the abduction, which might ruin our chances of helping to settle this peacefully in the long run. Then again, Yunzi might understand that we had good intentions, but that might not count for much when we're literally kidnapping her.
On the other hand, returning their Holy Maiden to them could be a show of good faith, and open up avenues to talk with them down the line. Yunzi, for one, should be willing to negotiate with us if the need arises, as she hasn't had problems talking to us before despite her cult's restrictions. Look at how Vairya obeyed her, when it came down to it. That might change if fuck up how we treat her here. But it could also mean that we lose contact with Yunzi entirely. However, the Cult has shown its willingness to talk to Jing before, way back at the tournament, and Vairya seems interested in Jing after his display of prowess, so we might have an in there.
Overall, this is a complicated issue that doesn't hinge completely on just the actions of Yunzi and Jing. She is a key player, yes, but both of them are just fucking teenagers at this point. Assuming that we know better than her is arrogant and patronizing. I just think regardless of whether we return her to the cult or not, there are uncertainties in all the choices regarding how the Fire Cult problems will play out, and we will need to make further choices down the line that will affect the issue more directly. And in that case, I much prefer the choice that doesn't treat Yunzi like an idiot or shortsighted for wanting to rush back and help her people.
Perhaps if
treave could elaborate on what Jing plans on doing with Yunzi in the case of a successful A and B? Because that "You will not let her go" makes me think of this image:
I feel like going with the A or B choices might just be personality-affecting decisions that turn us into this setting's Kinzo.
